commit 65271f868cb1dca709ff69e45939bbef8d6d0b70 upstream.
The function max14577_reg_get_current_limit() calls the function
max14577_read_reg(), but does not check its return value. A proper
implementation can be found in max14577_get_online().
Add a error check for the max14577_read_reg() and return error code
if the function fails.
Fixes: b0902bbeb7 ("regulator: max14577: Add regulator driver for Maxim 14577")
